The fans spinning up don't mean the computer is working. It only means the fans are getting 12 volts. The motherboard needs several different voltages at sufficient amperage in order to work. So it could be the power supply.

But first, did anything happen to it or did you make any changes between the last time it worked OK and the first time it didn't? Could someone else in the household have messed with it?

Otherwise, with the AC cord removed, open the case and temporarily disconnect the drives and remove any unneeded add-on cards. Remove any USB devices you have connected. Then reconnect the AC cord and power it up. If you get the normal posting or logo screen then one of the disconnected items must be at fault.

If you still get nothing it's probably the motherboard. Sometimes the capacitors go bad, especially those around the cpu. They'll get kind of a puffy look to them like a soda can that's been in the freezer too long and they'll be some dried residue on the top indicating leakage.

And sometimes a bad power supply will ruin the motherboard as well so it could be both of them. But hopefully you'll be able to isolate the cause to something not too complicated.

Are you using the on-board video circuit or an PCI-video-card?
If you have both, remove the video card and connect to the on-board video circuit.

Reset the BIOS by removing the coin-battery of a few minute or use the designated on-board jumper.

Okay, guys I got the computer to work! But one more question...
When I turn on the computer it starts up on a black screen reading something along the lines of your Floppys failed, but there is no floppys and it also says in parenthesis 40... It also says press F1 to continue and press F2 to open the settings..
Can anyone help me?
(Dont know if this helps or not but it has Windows Vista)

F2 to open settings should take you to the BIOS. You should disable the floppy drive in the boot priority sequence if there isn't one (a floppy drive).

It's a concern that your computer doesnt progress along to the next bootable drive such as CD/DVD or HDD though. First disable floppy drive from the boot sequence then see if your PC bocomes bootable or you get another error message.

What is the make and model of your computer?

Here is a video guide on changing the boot priority in the BIOS. It should give you the gist on how to do it on yours:

Edit: if HDD is disabled in the BIOS it needs to be re-enabled. Most have CD/DVD as first boot device and HDD as second boot device. That is a matter of preference though. The most important thing at this stage is to make the HDD enabled and for the purposes of troubleshooting put it at the top of the boot priority order.

Hey BtK. So I did as you suggested and changed around the priority of all the hard drives and such and originally it was 1. diskette drive 2. hard drive and then I changed it to 1.hard drive and 2. diskette drive but it still showed up with the same error message with the floppy drive (40).

In addition to my post #6.

Go into the Bios, STANDARD CMOS FEATURES. Next to drive B, use the Page Up key until the drive turns to 'None'. Reboot the computer. If you still get the message, go into the BIOS again, and select ADVANCED BIOS FEATURES. Find where it says 'Swap Floppy Drive Letters' or similar. Make sure it says disabled. Boot Up Floppy Seek, set to Disabled.

Yeah, in your # 7 all you did was change the boot drive sequence. You didn't disable the floppy drive or the floppy controller. So the bios is still expectiong a floppy drive to be there.

Possibly your cmos battery is dead and it's not holding the changed settings. The battery will be the silvery colored disk on the motherboard about the size of a nickel. If changing that doesn't fix it then recheck your cmos settings. You must be missing something.

I know that I have windows vista, the computer is a Dell XPS 630i, and that it has a Nvidia Geforce 9800 GT in it, 4g of ram, 64 bit, and that it has a intel duel core.

Thanks John!!! It worked when I did that! I have one last question though... Was it bad that it said that error message? Or like what did it do to the PC? Or was it just some little bug?

"It worked when I did that!"
Good news.

"Was it bad that it said that error message? Or like what did it do to the PC? Or was it just some little bug?"
No idea about any of that Cewpa, time will tell.

What I do know, is if you had given me the info in my post #14, by using MiTeC System Information X & Free PC Audit, it would have been a heck of a lot easier for me.
